Maxibright Compact ballast's from UK manufacturer Maxigrow are built using high-quality Venture control gear. Sealed in resin, they have all of the features you have come to expect from a top end ballast including silent running, thermally protected ballast, Digital SMART ignitor and double earth insulation. Maxibright Compact ballast's are compatible with both HPS and Metal Halide lamps.

Air is usually pulled (but can be pushed) over the lamp by adding an extractor fan to one side of the tube, the hot vented air is then expelled away from the grow room and plants. They're very effective, somewhere in the region of 70-80% of heat is removed, and are therefore very popular with indoor gardeners who have limited space to work with.

The Sunmaster range of HPS lamps have fast become our most popular high-pressure sodium flowering/fruiting lamp. This is mainly due to they're higher than most lumen count, and very reasonable cost! Sunmaster Dual spectrum lamps have a higher Red and Blue spectrum output than most brand name HPS lamps, which makes them ideal for those using one lamp for both vegetative and flowering phases.

For multiple 120mm Coolshade:
We recommend running up to 2x 250/400w lighting systems in a row using 2x 120mm Coolshades and a 125mm Rhino Single Speed fan.

For multiple 150mm Coolshade:
We recommend running up to 3x 600w lighting systems in a row using 3x 150mm Coolshades and a 150mm Rhino L1 Single Speed fan.

*PLEASE NOTE: 600w grow lights are supplied with a PRO Compact 600w ballast and not the cheaper Mk2 ballast which has been known to fail due to heat build-up. This stated difference is only relevant to the 600w Compact Ballast.
